FLUSHING-VALVE MECHANISM.

To all whom it may concern:

Be it known that I, JOHN W. MEAKER, a citizen of the United States ofAmerica, residin at Detroit, in the county of \Vayne and tate ofMichigan, have invented certain new and useful Improvements inFlushing-Valve Mechanism, of which the following is a specification,reference being had therein to the accompanying drawings.

In the operation of flushing valve mechanism it is desirable that thearrangement be such as will insure ease of operation as well asstability of the parts, together with such design as will enable thedevice to be mounted and dismounted at will readily.

This invention relates to mechanism for operating flushing valves and toan arrangement thereof whereby movement of the handle in eitherdirection from neutral or closed position throws the mechanism intoreleased or open position, the parts being so disposed as to bring theapplication of power to a valve operating member close to the load pointthereby insuring ease of operation.

The invention consists in the matters hereinafter set forth and moreparticularly pointed out in the appended claims.

In the drawings :F igure 1 is a view in front elevation of a mechanismembodying the invention with an operating handle in closed position;Fig. 2 is a view showing the mechanism moved into opened position bymovement of the handle in one direction from the neutral point; Fig. 3is a similar view showing the handle moved in the opposite direction;Fig. 4. is a plan view, partially broken away, of the mechanism; Fig. 5is a view taken in section on or about the center of motion of thehandle; Fig. 6 is a view of a mechanism showing a slight modification"in the slide member; Fig. 7 is a view in detail of the slide operatingcam; and Fig. 8 is a view in detail of anoperating lever pivotconnection.

Referring to the drawings a cylindrical sleeve 1 is arranged to besecured in an opening of a tank wall 2 on the inner face thereof as bymeans of a suitably disposed nut 3, the sleeve and nut constituting ahousing in Which the shaft 4 of an operating handle 5 is rotatablymounted. Preferably the shaft is squared or polygonal to nonrotatablyengage and carry a cam member 6, which plays in guide slots 7 of thesleeve 1. The shaft may be secured in position Specification ofLetterslatent.

in the sleeve. The bushing 12 looks the plate in position' but does notact as a bearing for the shaft which is loosely movable therein. A valveoperating lever 12 reciprocatesin suitable slots 14: in the sleeve 1,being pivoted therein by a bushing 13 which also operates as a bearingfor the shaft 4:. A guide member 15 which may be in the form of a rodwhose inbent ends are riveted or otherwise made fast to the plate 10cooperates with the latter to guide the lever 27. This guide member alsocooperates with other guide projections 16 or ears to limit the movementof a slide member 17 that is longitudinally reciprocable in a planeparallel to the plane of oscillation of the lever while the inner endportions of the slide embrace the sleeve 1 and abut a projection 18 onthe member 6. The outer end face 19 of the slide member is arranged tooperate as a cam to underrun and lift a stud 20 on the lever 27 when theslide is shifted and thereby raise the outer end of the lever. Afriction roll 21 may be provided on the stud if desired. As a furtherdetail of construction there may be an upturned end portion 22 on theslide to check the lever when the handle moves quickly back to neutralposition past which point its inertia is liable to carry it.

As hereinbefore described the cam face 19 is on the outer part of theslide, the latter being built up of a suitable rod with outturned endportions 23 to engage the mem ber 18. Other constructions of the slide,may of course, be used. One such modification is indicated in Fig. 7 inwhich the slide has an inner beveled face 24 engaging the stud of thelever, the member 6 being reverse in position with the extension 18operating to move the abutting ends 25 of the slide inward when thehandle is operated.

As a :esult of this construction a valve operating mechanism is obtainedthat not only works very freely but maintains its position when onceassembled. As the slide engages the lever at a considerable distancefrom the shaft the power arm of the lever is suflicient to raise thelower end very readily. The distance of the application of power to thelever from the pivot center of the latter may obviously be varied tomeet the requirements of service. The latch plate by which the shaft isretained in' the sleeve is readily disengaged and permits thedismounting of the entire device and its reassemblage without the use oftools, the bushing being readily pushed out to permit {he withdrawal ofthe guide plate and the ever.

Obviously, changes in the details of construction may be made Withoutdeparting from the spirit of my invention and 1 do not care to limitmyself to any particular form or arrangement of parts within the scopeof the appended claims.

What I claim is l 1. Mechanism for operating a flushing valve comprisinghousing means adapted to be secured in an opening of a tank wall, arotatable handle member mounted therein, a guide member detachablymounted on the housing member, a slide member reciprocable on the guidemember operatively connected to the handle member, and a valve operatingoscillatory member pivotally mounted on the housing and shaft andengaged by the slide, the slide being projected when the shaft is turnedin either direction from neutral position.
